Land Rover Discovery 3.9i 96
After start I feel the rpm go up and down, but don't see it on the tachometer, so on gear.
After the vehicle starts to warm up, the tachometer go up and down several times, till the point that it stall, when idle or in gear.
The warmer the car, the faster he stall.
Smell and feel as if the mixture is too rich.
The following have been made (none of them improved the situation):
Replaced (new) - fuel filter, stepper motor, O2 sensors, Injectors (mod),
Coil and module (mod (BEE)), Spark plugs and wires,
Alternator
Crossed - fuel pump, AFM, TPS, fuel temperature sensor, Distributer, ecu.
Adjust - AFM (1.8), TPS (0.3)
Checked - All vacuum hose.
Cleaned - AFM, throttle housing, oil filter separator, stepper motor.
I probable have forgotten some things, but by throwing your ideas, I'll remember. I have some ideas for the next steps (ideas much more radical) but let's hear you first!
